PROCESS OF ERECTING CONCRETE BUILDINGS.

Application filed August 19, 1925. Serial No. 51,235.

In erecting concrete buildings moulds are used, between the vertical walls of which a wet mixture of sand and concrete, hereinafter termed a concrete mixture, is poured, to obtain the walls of the building, the window and door frames of the building being properly placed between said vertical walls to be embedded in the concrete obtained by the setting of said mixture, and in erecting a building bythis process said moulds and additional ones are employed whereby the walls erected by this process contain vertical spaceswhich are sealed at their upper and lower ends, and a substantially horizontal mould, having sides and ends, is used to obtain the roof of the building, together with additional moulds whereby a number of sealed spaces are obtained in said roof.

Among the objects of this invention is to obtain a process whereby the walls of the building have sealed air spaces extending vertically from substantially the base of the walls to the top thereof, or substantially so; said walls provided with door and window frames embedded therein, and the walls below said window frames being provided with similar sealed air spaces extending from substantially the base of the wall to the lower horizontal members of said window frames, and from the top horizontal member of said door and window frames to substantially the top of said walls. A further object is to obtain a process whereby the walls of the building will contain reinforcing rods and wires, and the inner and outer portions of the walls will be substantially separated by the air spaces in said walls, and joined together by metal ties. An additional object is to obtain a process of erecting buildings whereby the roof of the building will contain a number of air spaces, with concrete above, below and between said air spaces. An additional object is to obtain a building erected by my process the outer portion of the walls whereof will not crack or become injured by rain, snow, or considerable variation in climatic temperature in the day and in the night; and a concrete building whereof the inner portion of the walls will be dry, and not affected by the wetting or moisture of the outer portion of the wall, as by rain or snow.

shown in Figs. 1, 4 and 5.

I have illustrated my invention applied to the erection of a concrete building in the drawings referred to, in which 1- Fig. l is a perspective of a portion of the side walls and roof of a partially erected building being constructed by my process; parts being broken away and removed to show the several members used in the construction of the building and the parts forming the elements of the building, and their relation to each other.

Fig. 2 is a plan view of a metal sheet which is formed up to form a mould for obtaining the air spaces in the walls of the building.

Fig. 3 is a perspective, on an enlarged scale, of the mould obtained from the sheet of metal illustrated in Fig. 2, and of a removable brace applied to said mould when the same is in position to be embedded in the walls formed by the pouring of a cement mixture around it.

Fig. 4 is a top plan view of a section of a wall, taken on line 44; of Fig. 5, viewed as indicated by arrows.

Fig. 5 is a vertical section of the section of wall illustrated in Fig. 4, taken on line 5 5 of Fig. 4, and viewed in the direction indicated by arrows.

Fig. 6 is a top plan view of a section of the roof of the building being erected, with portions of the several elements forming the roof removed, to show the construction thereof and the relation of said elements to each other, and

Fig. 7 is a vertical sectional view of the section of the roof which is illustrated in Fig. 6, taken on line 77 of Fig. 6, and viewed in the direction indicated by arrows.

A reference character applied to designate a given part indicates said part wherever the same appears throughout the several figures of the drawings.

1, Fig. 2, represents a sheet of metal,-

which is formed up substantially on broken lines 2, to obtain the collapsible mould 3, illustrated in perspective in Fig. 3, and The ends 4 of the collapsible mould 3 are rounded. 5 represents a piece of grooved and tongued flooring, which is of substantially the same length as the height of mould 3. 6 represents one end of the blank 1, which is bent inward to form a member adapted to lit in the groove of member 5. When member is in the position illustrated in Fig. 3 and as shown by full lines in Figsd and 5, said mould 3 is not collapsible; but when said member 5 is forced into the position indicated by the broken lines 7, in Fig, 4, it may be collapsed sufficiently to loosen the round ed ends 4:, so that said mould can be removed from the partially set concrete mixture surrounding it,

To construct walls by this process a trench is dug, and the base 8, Fig. 5, is pouredfrom a concrete mixture, and allowed to partially set. The outer moulds 9, 10, are built up on said base, to a height substantially corresponding with the height of mould 3, and said moulds are set on said base, together with reinforcing material 11, and reinforcing tie'members 12. The vertical reinforcingro'ds 13 are also set in place, the lower ends thereof preferably forced into the base 8. 'Said reinforcing rods 13 being positioned while said base is sufficientplastic to permit said rods to be forced th'ereihto. A concrete mixture is then poured between moulds 9 and 10, and around moulds '3, and around and over the several reinforcingmaterial and rods, to near the upper -edges of moulds 3. The mixture is allowed toparti'ally set, so as to retain its form, and thereupon members 5 are removed from moulds 3, and said mo'ulds are raised, so that the lower edges thereof extend a shortdistance below the upper surface of said concrete. The moulds 9 and 10 are raised, or built up, (as preferred), so that the upper edgesthereof are at substantially the same level as the upper edges of moulds 3. Additional reinforcing members are then placed in position between moulds 3 and 9 and 10, and additional concrete mixture is poured, as before.

V The foregoing process is continued until the walls are completed.

14, Fig. 4, represents a inember'of a door casing, and 15, 16 mould boards which extend from moulds 9 and'lO, respectively, to said casing 14. hen the concrete mixv'tur'e is poured as hereinbefore recited, the

casing ltbecomes'embedded in the wall.

Whenthe 'walls'have been erected to a de t rrni'ned height in the manner 'hereinbefore "described, the moulds 3 are removed, and the upper ends of the several air spaces formed thereby are covered, as by a thin sheet of, metal. The substantially horizontal mould bed, "17, Fig. 7 is then erected, with the up'perface thereof a short distance below the upperends of the walls, both on the inside of the walls, and on the outside 'ofthe walls. Said mould bed on the ,inside jof the wallsextends from wall to wall, and on the manner-tie distance corretially embedded in the concrete; and moulds 20 are then placed on the concrete mixture, to obtain substantially similar spaces between said moulds. Additional concrete mixture is then poured '"in' said spaces between moulds 20 to a cletermined height.

The last named mixture is allowed to par tially set, at least sufiicient to permit the 'withdra-walof the moulds 20 without disturbing the concrete walls around the several spaces which are obtained by the removal of. said moulds. The upper. ends ofsaid spaces, (designated by Figure 21 in Figs. 6 and 7), are then co'vered by a layer of building paper, 22, which extends entirely over the roof. A layer of woven wire, 23, is then placed on the building paper 22. 'A concrete mixture (23 is then poured on to the woven wire and building paper, to obtain a determined depth, and the additionalreinforcing members 24, 25,

are placed "on said mixture. Additional concrete mixture, 2 l is then poured over said additional reinforcing members and on to said thin -layer of concrete, 'to obtain the desired depth ofconcrete, and all the concrete mixture in the roofis allowed tofirmly set. The mould bed '17 is then removed and the walls and roof or the building "arecompleted,

By using proper material, with or without designs thereon, as preferred, on the uppenface of mould bed 17, the under surface of the roof serves as a ceiling'to the rooms and walls of the building. 26 represents an -I-beam, which I usejwhen the distance from wall to wall is so great that the roof constructed as described is liable to sag or give way.

Iclaimi- The process of constructing a roof to a building which comprises the pouring of a concrete mixture on a mould bedand between moulds in spaced relation to each other and to said mould bed, withdrawing said moulds from said concrete, placing building paper'over said concrete and over the spaces formed by the moulds, placing wire nettingfand reinforcing material over said paper, and pouring additional concrete mixture oversaid paper, said wire'netting and said reinforcing material.
